I've had my iPhone 4 since Christmas and for the first two weeks it was perfect. After that, the home button has been sticking quite a lot, and it has been getting A LOT worse. It's getting to the point where it's unusable. It sometimes recognises single clicks as two clicks and then sometimes it doesn't register clicks at all. I was wondering if I could take this to an Apple Store and have it repaired/replaced as this is really annoying and well, for such an expensive phone, I'd expect it to work still in the first month.
